All Pokemon have the ability to learn various attacks that they can use to fight other Pokemon, and many of the moves simply make no sense, whether from the anime or the games. In the games, some Pokemon can learn moves that their body simply should not be able produce, whether because of laws of physics or simply that the Pokemon has no arms... Here, a couple instances of Pokemon using moves that they physically should not be able to learn will be discussed.

Field Moves in the Games

One of the most commonly questioned aspects of the Pokemon games is how some Pokemon can learn Hidden Moves (or HM's) that usually involve the Pokemon using them transporting the player character around, like carrying them through water, or carrying them through the sky. The only problem is that many of the Pokemon are very small and would most likely not be able to carry the player.

For example, Pidgey is a bird Pokemon that bears some resemblance to real life birds like sparrows. Pidgey, unsurprisingly, is relatively small compared to most Pokemon, measuring only 1 ft, or 0.3 m in height. What is surprising, however, is Pidgey's ability to learn the Hidden Move fly, which allows Pidgey to carry the player through the sky. If the player character in the game is assumed to be around 10 years old, he or she would probably weigh somewhere around 75 lbs, or about 34 kg. Using the equation for force, Force = mass*acceleration means that Pidgey would have to exert an upward force of (34 kg)(10 m/s) = 340 N just to counteract the acceleration due to gravity and hold the player, let alone fly with the player. In order to fly, there would need to be an overall acceleration in the upwards direction, meaning Pidgey would have to exert even more force to keep the player up. While something as small as 0.3 m tall could produce these forces, it is unlikely.

Another example is the Pokemon Rhyhorn, which is capable of learning a move called Surf, which allows the player to cross bodies of water while riding on their Pokemon. Rhyhorn however, is a rock type Pokemon, with the 'rhy' in its name most likely coming from rhyolite, a type of igneous, volcanic rock. Assuming Rhyhorn is made of a material with similar properties to rhyolite, Rhyhorn should definitely have a density much greater than water, with rhyolite having a specific gravity of 2.4-2.6, which means it is 2.4-2.6 times the density of water. Being made of some sort of similar material means that there is no way Rhyhorn should be able to cross the water, let alone with someone riding on its back.
